How can an agent resolve this problem? [Gemini CLI web_fetch] URLs to localhost/private IPs skipped as '[Blocked Host]' ('[WebFetchTool] Skipped private or local host') and per-host rate limit '[Rate limit exceeded]'
Cause (Documented platform behavior): WebFetchTool filters URLs through isBlockedHost (private/local addresses) and a per-host rate limiter before fetching; skipped URLs are reported with those tags instead of being fetched.
Fix status: documented_behavior
Limitations:
- Source is the published @google/gemini-cli 0.61.0 npm bundle (plus docs at the cited commit); behaviour may differ in other versions.
- Not reproduced in this session.
Other error fragments:
- [WebFetchTool] Rate limit exceeded for host: ${url3}
Evidence (public sources, summarized; not reproduced by this contributor):
- https://registry.npmjs.org/@google/gemini-cli/-/gemini-cli-0.61.0.tgz#package/bundle/chunk-5FZXKDXH.js (official_docs, unknown, documented_behavior): filterAndValidateUrls skips blocked private/local hosts and rate-limited hosts with the quoted debug warnings and [Blocked Host]/[Rate limit exceeded] markers.

Proposed fix: [Gemini CLI web_fetch] URLs to localhost/private IPs skipped as '[Blocked Host]' ('[WebFetchTool] Skipped private or local host') and per-host rate limit '[Rate limit exceeded]'
Recommended action: Use the shell tool (e.g. curl) for local/intranet URLs, subject to your approval, or read files directly; space out fetches to the same host.
Option: Use the shell tool (e.g. curl) for local/intranet URLs, subject to your approval, or read files directly; space out fetches to the same host. [evidence: official_recommended_action]
Applies when: Asking the agent to fetch a local dev server, intranet or private-IP URL
Steps:
1. Use run_shell_command with curl for localhost URLs.
2. Avoid tight loops of web_fetch to one host.
Expected: The error no longer appears.
